The complexes [Pt(ER)2(L–L)[ER = SPri, SPh, C6H4Me-p or SePh; L–L = Ph2P(Ch2)nPPh2(n= 1–3)] have been prepared and their ability to act as bidentate ligands towards other metal species demonstrated. Proton, 31P and 195Pt NMR spectroscopy have been employed to ascertain their structures. A single-crystal X-ray structure determination of [Pt(SePh)2(Ph2PCH2PPh2)] has established the mononuclear nature

Mononuclear palladium and platinum complexes of the type M(ER)(2)((PP)-P-boolean AND) [M = Pd or Pt; ER = SPh, SC6H4Cl-4, SC6H4Me-4, SC6F5, SePh, TeC6H4OEt-4; (PP)-P-boolean AND = dppm or dppe] have been prepared and their ability to form dinuclear metal species has been demonstrated. All complexes have been characterised by multinuclear magnetic resonance (H-1, C-13, Se-77, Pt-195) spectral data. The effects of phosphine ligands and organochalcogenides are reflected in the Se-77 and Pt-195 NMR shifts. The shielding of Pt-195 NMR chemical shifts has been interpreted in terms of their binding ability to platinum. The structures of two derivatives, namely [Pd(SC6F5)(2)(dppe)] and [Pd(SePh)(2)(dppe)], have been established by X-ray crystallography. The palladium atom in each of the monomeric structures exists in a square planar geometry. (C) 1999 Elsevier Science S.A. All rights reserved.
